Free: Contests & Raffles.
All good add ons so far, i would check the weather and add sunscreen and TP/Wetwipes and i carry disposable gloves. also bottled water even with the camel back Also i always wonder why some people carry some things in there pack, i like to keep it useful but simple and light as possible (not an extremist backpacker by any means) but 2 things i would change 1) ammo in holder on your belt or on the rifle stock 2) whats in your kill kit that you need other than the knife, bags and para cord mentioned separate?
Trekking poles . dry sack . extra socks and sports tape. Couple rolled up garbage bags and some para cord ...puffy top and bottoms.headlight with extra batteries. I download the area on hunt onyx so I can use GPS in phone.
